The morbid but perennially accurate music industry adage that few things boost sales more than an untimely demise has been proven again in this week's UK charts, which features Amy Winehouse's Back to Black as the bestselling album.

No fewer than five of her singles are also in the top 40. Back to Black, the second of just two albums by the hugely talented but vulnerable singer, who was found dead just over a week ago, aged 27, returned to the top spot for the first time since its release in 2006.

Winehouse's 2003 debut, Frank, was at number five, a considerably higher position than its previous peak of 13. A boxset of the two albums, which is counted as a separate release, entered the chart at 10.

It was a similar story in the singles rundown where five songs from Back to Black, a melancholic collection largely inspired by a romantic loss, entered the top 40.

The title track charted highest, at eight, with Tears Dry On Their Own at 27, Rehab at 29, Love is a Losing Game at 33 and You Know I'm No Good at 37.
